What does argus mean?
An Argus is, at its heart, a symbol of unblinking vigilance. The word derives from Argus Panoptes, the hundred-eyed watchman of Greek mythology who guarded Io on Hera's behalf until Hermes lulled him to sleep and killed him. Since classical times, writers have invoked Argus to describe any tireless observer — a strict supervisor, a censorious public, or, in modern usage, surveillance technology. The word also survives in natural history as part of the names of strikingly marked creatures: the argus pheasants of Southeast Asia, whose wings bear large ocellated 'eyes,' and the argus fish of South America, spotted like a peacock feather. Most commonly met today in the form 'argus-eyed,' meaning extremely alert and observant, the term carries connotations of scrutiny that can be protective or oppressive depending on context. It remains a vivid literary shorthand for being watched.
A watchful guardian or vigilant observer, alluding to the hundred-eyed giant of Greek mythology.
"To the students, the headmaster was an Argus who missed nothing."
Usually figurative or allusive; frequently appears in the derived adjective 'argus-eyed'.
Either of two birds (argus pheasants) of Southeast Asia noted for the large eye-like spots on their wings, or a spotted South American freshwater cichlid fish known as the argus fish or peacock-eye cichlid.
"The great argus pheasant fans its secondary feathers into a spectacular disc of staring eyes."
As an English count noun referring to the birds or fish, the standard plural adds -es; the mythological figure is usually treated as singular.
"Several arguses displayed simultaneously along the forest trail."
When Hermes slew the hundred-eyed giant Argus, Hera scattered his eyes onto the peacock's tail — which is why peacock feathers still seem to stare back at you.

Etymology of argus
The word comes directly from Greek Argos (genitive Argous), the epithet of Argus Panoptes, the 'all-seeing' giant whose body was covered in eyes. Latin adopted the name as Argus, and it passed into English in this form by the early modern period. The same Greek root underlies related terms such as Argonaut, one of the heroes who sailed with Jason aboard the Argo. The transferred sense of a watchful person has been current since antiquity, while the zoological applications arose later as naturalists named eye-spotted birds and fishes after the mythical figure.
